Referring to the first configuration of the present invention with reference to Figures 1 and 2, the present invention is largely the case 100, decomposition tank 200, agitator 300, screw conveyor 400, heating unit 500 And a dehumidifying unit 600.

The case 100 has a predetermined receiving space formed therein to form the overall appearance of the present invention as shown in Figure 1 so that the other components listed above can be installed therein, and covers the inside so that the inside is not visible from the outside. It functions to shield the inside and the outside to prevent leakage of water vapor and odor generated during food processing.

One side of the case 100 is provided with an inlet 110 so that the food waste can be input, and the outlet 120 is provided on the other side, while the food waste is injected into the outlet 120 to remove moisture and a small volume. The compressed food solids are discharged.

Both the inlet port 110 and the outlet port 120 has a structure that can be opened and closed in the form of a door (sealing) of the rim sealing (sealing) so that water vapor and odor generated from the inside does not leak to the outside, in particular in the inlet 110 The door switch 112 is provided to know whether the inlet 110 is open or closed.

That is, the inlet 110 is provided with an inlet door 111 installed to open and close, the door contact 112 for detecting the opening of the inlet door 111 is provided in the contact portion with the inlet door 111 is provided. In the open state of the input door 111, the operation of the stirrer 300 to be described later is stopped, which will be described in detail later.

On the other hand, as shown in Figure 3, the decomposition tank 200 is configured to be installed inside the case 100 in a structure that the lower portion is narrowed so that the food introduced into the inlet 110 can be collected in the case 100. Invar, the digestion tank 200 is formed in the form of a "U" as a whole, the food waste introduced into the case 100 through the inlet 110 is to stay in the digestion tank 200.

Here, since the stirrer 300 is disposed inside the digester 200 and the screw conveyor 400 is disposed below the stirrer 300, the food waste is agitated toward the screw conveyor 400. The lower part of the digester 200 is open toward the screw conveyor 400 so that the food waste sent to the screw conveyor 400 is not dispersed around the screw conveyor 400 so that the lower part of the digester 200 is not disposed. Consists of a structure surrounding the conveyor (400).

In addition, the stirrer 300 is rotatably installed in the decomposition tank 200 to function to crush and mix the food gathered in the decomposition tank 200, the stirrer 300 is to enable such a function Figure 2 And a first driving motor 310, a rotating shaft 320, and a stirring blade 330 as shown in FIG. 3.

The first driving motor 310 is a bidirectional motor that is operated by receiving power and capable of both forward and reverse rotation, and according to a control signal of the controller 700, forward or reverse rotation of the first driving motor 310. This happens, the control unit 700 by mixing the food waste evenly and quickly by the forward or reverse rotation of the first drive motor 310 according to the set program so that the stirring is easily and quickly performed (see Fig. 6).

The stirring of the food waste is to save drying time and energy when the food is well mixed and subjected to the heating and grinding process.

In addition, the rotating shaft 320 is connected to the first driving motor 310 is a configuration that is rotated by receiving a rotational force from the first driving motor 310, the stirring blade 330 to the rotating shaft 320 It is formed in a cross direction and is disposed at a predetermined angle on the rotary shaft 320 like a fan blade so that the food is moved in the direction of the rotary shaft 320 when stirring. For example, the stirring blades 330 are formed to protrude in a direction perpendicular to the rotation shaft 320, and the planes formed by the stirring blades 330 are disposed to be inclined at an angle.

As the stirring blade 330 is formed to have a predetermined angle on the rotating shaft 320, when the rotating shaft 320 is rotated, the stirring blade 330 mixes the food waste collected in the decomposition tank 200 as well as the primary. The food waste is moved in either direction according to the rotational direction of the rotary shaft 320.

As such, when the stirring blade 330 moves the food waste, the food wastes are compressed and crushed in the process of being moved, and the water contained in the inside is easily discharged, and the food waste being moved inside the case 100. When it hits the wall, the effect of crushing and crushing is doubled, which can further enhance the effect of crushing and stirring food waste.

In addition, when the rotation direction of the first driving motor 310 is changed by the control signal of the control unit 700, the above-mentioned effects of the crushing, stirring, and crushing of the food waste are further increased. When the trash was put into the mixing function, but was merely responsible for this, the stirrer 300 according to the present invention can see the effect of grinding and crushing primarily in the stirring process itself.

Here, the first drive motor 310 and the rotary shaft 320 may be directly connected to the shaft, but a large torque is applied to the rotary shaft 320 in the process of stirring food waste load of the first drive motor 310 In order to reduce the pressure, it is preferable that a first reducer 340 is provided between the first driving motor 310 and the rotating shaft 320 to facilitate the rotation of the rotating shaft 320.

The first reducer 340 is a device that is able to bear a large torque with a small torque by joining gears of different gear ratios with each other, and thus a detailed description thereof will be omitted.

In addition, it is preferable that the end of the stirring blade 330 is provided with a bracket 331 to facilitate the stirring by increasing the contact area with the food waste.

On the other hand, the screw conveyor 400 is disposed long in the disassembling tank 200 to be fed to the outlet 120 provided on the other side of the case 100 while being crushed to receive the food stirred by the stirrer 300 It is a constitution.

Since the lower part of the decomposition tank 200 is configured to surround the screw conveyor 400 while being opened toward the screw conveyor 400, the food waste stirred by the stirrer 300 is naturally sent to the screw conveyor 400. Lose.

As shown in FIG. 2, the screw conveyor 400 includes a second driving motor 410, a screw shaft 420, and a second reduction gear 430. The second driving motor ( The 410 is a bidirectional motor that is operated by a control signal of the control unit 700 as in the first driving motor 310 described above and is capable of both forward rotation and reverse rotation.

In addition, the screw shaft 420 is connected to the second drive motor 410 receives a rotational force and a screw thread 421 is formed on the outer peripheral surface, when the screw shaft 420 is rotated to the screw thread 421 The food waste is moved in either direction.

In addition, the second reducer 430 is installed between the second drive motor 410 and the screw shaft 420 to reduce the load of the second drive motor 410, the first reducer ( 340 performs the same function.

In this case, as shown in FIG. 5A, all of the threads 421 of the screw shaft 420 may be set in the same direction. When the threads 421 are formed in the same direction, the screw shaft 420 is formed. When the) is rotated in one direction, the conveying direction of the food waste also becomes one direction.

For example, when the screw thread 421 is formed in the form of a right screw on the entire screw shaft 420, the food waste between the screw threads 421 according to the rotation direction of the screw shaft 420 is either forward or backward. Is moved in the direction.

Here, the screw conveyor 400 is rotated in a direction different from the rotation direction of the rotary shaft 320 during the operation of the stirrer 300, as well as the transfer function of food trash of the food trash between the stirrer 300 It performs a crush function and a crushing function and continues to move in one direction again so that the food waste hit the inner wall of the case 100 to be compressed into a small volume.

As the forward and reverse rotation of the screw conveyor 400 is repeatedly performed, the food waste may be very finely ground and compressed into a small volume to become a solid having almost no moisture.

The forward and reverse rotation of the screw shaft 420 is operated according to the set program as the control unit 700, as in the rotary shaft 320 of the stirrer 300 described above, the program is appropriate according to the needs of the implementer For example, the stirrer 300 is rotated forward so that the food waste moves to the right in the drawing while the screw conveyor 400 reversely rotates the food waste to the left in the drawing. The food wastes are rubbed together by crushing, and the food wastes thus moved are compressed and compacted on the inner wall surface of the case 100. Then, the crushing and compacting actions are repeated by changing their respective rotation directions again. Can be set.

On the other hand, as shown in Figure 5b the screw thread 421 of the screw shaft 420 is set in a different direction with respect to the middle portion of the screw shaft 420 so that the food is different in the feed direction when the screw shaft 420 rotates It is also preferable to have.

As such, when the directions of the screw threads 421 are different from each other, for example, when the screw shaft 420 is rotated forward, food is moved to both ends of the screw shaft 420, or when the screw shaft 420 is rotated reversely. The screw shaft 420 may be moved to the middle portion, which also causes crushing and compacting of food in the screw conveyor 400.

As described above, when the directions of the threads 421 are opposite to each other, the crushing action of the food may occur during transportation, but the compaction may occur at both ends or at an intermediate portion thereof according to the rotational direction of the screw shaft 420. In particular, when the compaction of the food occurs in the middle portion of the food is pressed together with each other.

As described above, when the food is compacted to some extent by the rotation of the screw shaft 420, the food waste may be collected by opening the discharge port 120 formed at the other side of the case 100.

On the other hand, the heating unit 500 is provided around the decomposition tank 200, as shown in Figure 3, by heating and drying the food collected in the decomposition tank 200 to induce accelerated evaporation of moisture contained in the food It is a constitution.

In general, since the food contains a large amount of water, in order to process the food waste and make it into a small volume, water removal must be preceded. The heating unit 500 heats the food of the decomposition tank 200 to evaporate moisture. By inducing, it helps to minimize the volume of food waste, and in particular, it prevents the occurrence of odor by making the treated food solids contain little moisture.

Here, the heating unit 500 is provided near the decomposition tank 200 and the first temperature sensor 510 for measuring the temperature, and electrically connected to the first temperature sensor 510 and the first temperature sensor ( The control unit 700 for comparing the set value input therein to the measured value provided from the 510 and the heater unit 520 electrically connected to the control unit 700 and operated by a control signal of the control unit 700. (See Fig. 6).

The first temperature sensor 510 is installed near the decomposition tank 200 to measure the heat generated by the decomposition tank 200, the first temperature sensor 510 is typically inside the decomposition tank 200. The temperature of the food is measured, but if there is a lot of food, the temperature of the food may be measured by direct contact with the food.

In addition, the control unit 700 compares the measured value provided from the first temperature sensor 510 with a comparison value input therein, and when the measured value is larger than the comparison value, determines that the heater unit is overheated. 520 is turned off.

The heater 520 may be in direct contact with the food, but in order to extend the life of the heater 520, the heater 520 heats the decomposition tank 200, and the decomposition tank 200. The method of heat transfer to food again is preferred, in the embodiment of the present invention, the heater unit 520 is implemented in the lower part of the disassembling tank 200, but it is not necessarily limited thereto, and according to the needs of the practitioner Although design changes are possible, this also belongs to the scope of the present invention.

On the other hand, the dehumidification unit 600 is configured to be installed on one side of the inside of the case 100 to be evaporated by the heating unit 500 is filled in the case 100, the water evaporated from the food is It is present in the case 100 in the form of water vapor (humidity), in which case the water vapor is filled in the case 100 and saturated state is a saturated steam state that no longer evaporates even when the food is heated. Even though the sealing effect of the case 100 is excellent due to deterioration of food drying effect and odor, the odor leaks into the room.

Therefore, the dehumidification unit 600 immediately removes the water vapor filled in the case 100 so that the moisture contained in the food can be easily evaporated and at the same time prevents the occurrence of odor in the case 100. . Odor is a micro-molecule of food waste coexist in the air in the case 100 together with the water vapor, if the moisture vapor dehumidification can be largely removed.

As shown in FIG. 2, the dehumidification unit 600 includes an air supply pipe 610 for supplying dry air to the decomposition tank 200, and a recovery pipe for recovering steam generated from the decomposition tank 200. 620).

Water vapor evaporated from the food is introduced into the dehumidification unit 600 through the recovery pipe 620 and converted into dry air by the dehumidification action therein, and then into the decomposition tank 200 through the air supply pipe 610. It is supplied again, so that the decomposition tank 200 is not saturated steam, the water of the food may continue to evaporate.

Here, the dehumidifying unit 600 is circulated from the evaporator 630, the compressor 640, the condenser 650, the expansion valve 660 to the evaporator 630, as shown in FIGS. By forming one refrigeration cycle is to remove the water vapor (humidity) contained in the air through the evaporator 630, the operating principle is similar to the air conditioner.

Therefore, the air supply pipe 610 and the recovery pipe 620 communicate with the air duct 670 passing through the evaporator 630 to dehumidify the water vapor of the decomposition tank 200.

For reference, in the configuration of the dehumidification unit 600, the evaporator 630 cools the ambient air as the liquid refrigerant evaporates and absorbs the surrounding heat in the process of becoming a gaseous phase, and the compressor 640 is the evaporator 630. The action of sucking the refrigerant in the vapor phase evaporated from and to raise the pressure to the saturation pressure of the condenser 650 to discharge the refrigerant, the refrigerant is a high temperature and high pressure state through the compressor 640.

In addition, the condenser 650 allows the refrigerant of the high temperature and high pressure compressed by the compressor 640 to be condensed at room temperature and high pressure as it exchanges heat with ambient air at a lower temperature. It becomes a lower subcooled liquid and exits the condenser 650.

On the other hand, the liquid refrigerant from the condenser 650 is a low pressure through the expansion valve 660, the refrigerant is easy to evaporate, the low-pressure liquid refrigerant is recycled to the evaporator 630 to evaporator 630 The surrounding air is cooled. In this process, water vapor contained in the air condenses on the surface of the evaporator 630 and is discharged through the drain pipe 631 to lower humidity in the air.

In addition, the air duct 670 is preferably provided with a blower 680 to facilitate the blowing of dry air to the air supply pipe 610, in the embodiment of the present invention, the blower 680 is the evaporator ( It is implemented to be disposed at the rear end of the 630, but may be disposed in front of the evaporator 630.

In addition, a second temperature sensor 690 for measuring the ambient air temperature is provided on the discharge side of the dehumidification unit 600, the information measured by the second temperature sensor 690 is input to the control unit 700, the control unit The control unit 700 controls the operation of the compressor 640 by comparing the measured value measured by the second temperature sensor 690 with a set value set therein.

The reason why the second temperature sensor 690 is required is that the water vapor filled in the case 100 passes through the evaporator 630 and the dehumidification is performed, as well as the air temperature is lowered. This is because the humidity inside the case 100 can be relatively estimated by measuring the air temperature through 690.

Accordingly, the controller 700 operates the compressor 640 when the measured value measured by the second temperature sensor 690 is higher than the set value set therein, that is, when the air temperature is high, and the measured value is the set value. If it is equal to or lower than the stop of the compressor 640 to prevent power consumption.

In addition, the evaporator 630 is provided with a drain pipe 631 for discharging the condensate to the outside, the drain pipe 631 is formed with a U-trap (U-trap) for preventing odor leakage .

The utrap section 632 is a structure in which the path of the drain pipe 631 is bent once from the bottom to the top and then falls back to the bottom. When the utrap structure is formed, a portion of the drain pipe 631 is filled with condensed water. Therefore, the odor inside the case 100 is prevented from leaking out. For reference, the condensed water has no smell as water condensed in the evaporator 630 where the wet steam is cold.

In addition, the case so that the user can recognize various information such as the stirrer 300, the screw conveyor 400, the heating unit 500, the operation of the dehumidification unit 600 and the temperature inside the case 100 ( It is preferable that a screen portion 130 as shown in FIG. 1 is provided on the outer surface of 100.

As shown in FIG. 6, the screen unit 130 receives the information from the control unit 700 and displays the information so that the user can view it, and if necessary, the screen unit 130 is made of a touch screen that can be manipulated by hand. You can change the value entered in or control the operation of the internal device.

On the other hand, as described above, the inlet 110 is provided with a door switch 112 for detecting the opening of the inlet door 111, the signal of the door switch 112 is shown in Figure 6 the control unit When the opening of the input door 111 is detected, the control unit 700 stops the operation of the first driving motor 310 and the second driving motor 410 so that the input opening 110 is closed. In the open state, the stirrer 300 and the screw conveyor 400 are stopped.

In order to stop the operation of the stirrer 300 and the screw conveyor 400 in the state in which the inlet 110 is opened, the food waste that has been processed in the stirring process and the transfer process may flow out through the inlet 110. On the other hand to prevent this, to prevent the safety accident in which the user is injured in the rotating stirrer 300 and screw conveyor 400.

As mentioned above, although this invention was demonstrated in detail using the preferable Example, the scope of the present invention is not limited to the specific Example described, and the person of ordinary skill in the art is not limited within the scope of this invention.
